After a recent cyberattack on Japan Airlines (JAL), Japan’s largest mobile carrier, NTT Docomo, became the latest victim of a cyber intrusion. The attack, which took place early today, caused significant disruptions to the company’s bill payment services, leaving a large number of users unable to complete their transactions. Fortunately, reports indicate that the attack did not lead to any breaches of communication or personal data, sparing citizens from more severe consequences.
To understand the nature of the attack, it’s important to explain what a Distributed Denial of Service (DDoS) attack is. In a DDoS attack, malicious actors flood a company’s servers with an overwhelming amount of traffic, which is often generated by networks of infected devices, or “bots.” This influx of data overwhelms the system, causing it to slow down, crash, or become completely inaccessible. The primary aim of a DDoS attack is not to steal data but to disrupt the normal functioning of services. In this case, it seems that the attackers aimed to paralyze Docomo’s payment systems, likely in an effort to cause operational chaos.
While the identity of the attackers remains unknown, cybersecurity experts are speculating that the strike could be the work of state-sponsored hackers. Such attacks are often politically or economically motivated, with perpetrators either aiming to make a statement on the international stage or to influence a targeted country’s political and economic decisions. These types of cyber incidents are typically well-coordinated and can cause widespread disruption, often drawing media attention to the state of a nation’s cybersecurity infrastructure.
NTT Docomo, whose name translates to “everywhere” in Japanese, is a household name in Japan, serving as the nation’s largest mobile carrier. As of 2021, the company boasted a customer base of over 81 million users, cementing its position as a crucial player in Japan’s telecommunications sector. Offering services across 2G, 4G, and 5G networks, Docomo provides a broad array of mobile services, including voice calls, SMS, and video calling, all available nationwide.
In fact, Japan has been a pioneer in mobile technology, and NTT Docomo has played a leading role in this. Back in 2020, Japan became the first country in the world to roll out 5G services to consumers, making it a leader in the next-generation wireless technology race, ahead of China and the United States. Looking to the future, Japan is already preparing to test the early phases of its 6G network, which is expected to deliver even faster speeds and more reliable connections. In anticipation of this, Japanese manufacturers are already producing smartphones equipped with 6G capabilities, designed to address some of the cybersecurity vulnerabilities found in current 5G networks. These innovations suggest that Japan is not only focused on maintaining a competitive edge in the global telecommunications market but also on securing its future in the face of rising cybersecurity threats.
Despite the ongoing challenges posed by cyberattacks, Japan’s telecommunications industry is likely to continue evolving, with companies like NTT Docomo at the forefront of both technological innovation and the ongoing battle to protect their infrastructure from malicious actors.
